[PATCH RFC 0/4] vsock/virtio: optimizations to increase the throughput
This series tries to increase the throughput of virtio-vsock with slight
changes:
- patch 1/4: reduces the number of credit update messages sent to the
transmitter
- patch 2/4: allows the host to split packets on multiple buffers,
in this way, we can remove the packet size limit to
VIRTIO_VSOCK_DEFAULT_RX_BUF_SIZE
- patch 3/4: uses
